Is this a "why not" for everyone who is rebuilding an engine or does it make no difference unless you are seriously racing? It seems that you would have a smoother running engine if it was all balanced well.

My view is that the rods should always look like the pictures above, any engine. Biggest reason, stress risers, ie scratches, or gouges or sharp or rough edges will cause cracks to start and the part to fail even street cars. As for balance it makes any engine run longer, smoother. Better than production Porsche balance? Maybe overkill.
For any race car or really HP street car you should also have everything shot peened. This puts the entire surface of the material in compression, which prevents cracks from propagating or even starting. If you do balance your rods you should send them out to be shot peened after you balance them.
